ZT-75/150AT Rock Rig for 204m Dual-Guidance Electrical Project in Riyadh

Project Overview

A 204-meter electrical pipeline project in Riyadh deployed the ZT-75/150AT rock drilling rig as the primary equipment. The project required the construction of two guidance holes, and the ZT-75/150AT rig accomplished two smooth guidance drilling runs to complete the task.

• Drilling length : 204m
• Water comsuption : 100-140L/min
• Final total capacity : 218CBM
• Rod length : 4m
• Speed per rod : 15-23mins/rod
• Inner rod torque : 3200-3800n.M
• Mud pump displacement : 800L/min

Equipment in Action: ZT-75/150AT

The project leveraged the robust capabilities of the ZT-75/150AT, a rig engineered for demanding rock conditions and long-distance drills.

• Superior Rock Drilling Power: Equipped with a high-torque system delivering 35,000 N.m for external drilling and 4,700 N.m for inner drilling, providing exceptional performance in challenging strata.
• Massive Thrust & Pullback Force: A formidable 1,500 kN of thrust/pullback force, combined with a pullback speed of 50 m/min, ensured efficient and controlled rod handling over the 204-meter span.
• High-Capacity Fluid System: The integrated mud pump (800 L/min at 10 MPa) delivered reliable borehole stability and cuttings removal, which is crucial for successful pilot hole completion in extended drills.
• Optimized for Large-Scale Projects: Utilizing φ102/60*4000 mm drill rods and compatible with reamers from φ300-1000 mm, the rig is built for significant pipeline installations. Its dimensions (10500*2500*2700 mm) and weight (24,500 kg) provide a stable platform, while a 2.5 km/h walking speed ensures good site mobility.

This project in Riyadh demonstrates the ZT-75/150AT Rig's capability to execute precise, long-distance pilot hole drilling in complex projects. Its power, stability, and reliability make it an ideal solution for large-scale infrastructure work in the utility and energy sectors.
